[squid-users] superfluous DNS queries

Hello,

I set up SQUID to forward all HTTP traffic through a parent proxy
(bound to internet) except when URL matches certain suffix domains (intranet).
Upon receiving internet URL like www.thepurists.com, SQUID however
queries DNS servers for www.squid-cache.org, www.squid-cache.org.sub.my.org, ...

Is it possible to prevent that behavior ?

Indeed, i dont know anyone who who type in a browser:
http://www.squid-cache.org. instead of http://www.squid-cache.org

So i believe it would be nice if SQUID processed URL having at least one dot
as if there were fully-qualified.
